I IGNITION SYSTEM FOR EXPLOSION-ENGINES.

Specification of Letters Yatent.

Patented Apr. 9, 1918.

Application filed August 22, 1916. Serial No. 116,283.

To all whom it may concern:

Be it. known that l, HENRY A. Lyon, a United States, residing atSolomon, in the county of Dickinson and State of Kansas, have inventedcertain useful Improvements in lgnition Systems for Explosion-Engines,of which the following is specification, reference being bad therein tothe accompanying drawing.

This invention relates'to improvements in circuit. closers and is moreparticularly minptcd to control the ignition system of internalcombustion engines. To this end I provide :1 switch which is operatedmanually to connect the spark plug ignition for energizntion but which,when released, will autonmtically disconnect the same and connect themake and break ignition, operating in conjunction with the jump sparkignition of the engine.

In the nccompanyin drawings:

Figure l is :1 top p on View of the complctc switch, the electricalcircuits bein in diagram. heavy lines indicating the fiow of currentwhen the jump spark ignition is energized.

Fig. 2 is of Fig. 1.

Referring a cross section taken on line 2--2 to the drawings, thenumeral 5 designates the switch casing which is made in the form of acup-and preferably of insulating material.

Mounted within this cup are two sets of metal contact strips 6 and 7.the strips 6 being connected through the binding posts 8 with the makeand break ignition system, to be hereinafter explained in detail, whilethe strips 7 are connected through the binding posts 10 in the jum sparkignition system designated generally by the reference numeral 11.

Mounted within the cup is a bar or rod 12, whose terminals are seatedrespectively in the socket 13 and the opening 14 of the cup, while theflattened apertured portion 15 thereof receives the bolt or screw 16which rigidly secures the same to the bottom of the cup.

The switch member 17 is made from a 'single piece of material andcomprises the in tel-mediate port-ion 18 having the elongated slot 18which for the bar, while the two depressed contact shoes 19 and 20 aredisposed to resiliently engage either of two pairs of the respectivecontact strips 6 and 7, either the first and surrounds the attachingscrew third or the second and fourth contacts (it being noted that thespan of these depressed contact shoes is such as to connect two contactstrips and bridge over a third contac strip), to form a closure toeither one of the ignition circuits.

The upwardly projecting terminals 21 and 22 of the switch have apertures23 and 24: which fit slidably upon the cylindrical terminals of the bar,while disposed upon one of the terminals of the bar and against the wallof the cup adjacent the socket thereof. is a coil expansion spring 26which normally holds the switch in contact with the first contact strips6 and 7.

The wiring system of my invention will now be described. From, one sideof battery 5' leads a wire 9 to the switch member 4 from which leads awire 1' connected to the first contact strip 6. The first contact strip6 and the third contact strip 7 are bridged by the switch member 17 andconnected to this third contact strip 7 is a wire 13 lead ing to themake and break system 30 of the engine frame, thence current flows byway of the wires 12 and wire 11' to switch member 10' and thence by wayof lead wire 9 back to the other side of the battery. Thus when theswitch member 17 connects the first and third contact strips, after theengine shall have been initially started'and the switch member 17 hasjust been released from the tension of spring 26, the current will flowby way of the first and third contact strips, and the engine frame toboth sides of battery 5' and consequently ignite the charge within thecylinder. and keep the engine running. The second and fourth contactstrips are also adapted to be connccted by switch member 17. The wire 9leads from one side of the battery 5 by way of wire 17' to secondcontact strip 6, and a wire 16' leads from the fourth contact strip 7 tothe primary circuit, of the coil box .15; thence a wire 18 runs fromcoil box 15 to wire 11 which conducts current by way of switch 10' andwire 9' back to the other side of the battery 5'. Thus to initiallystart the engine the switch member is manually pressed against thetension of the spring 26 so as to bridge the second and fourth contact,strips and be held out of contact with the first and third contactstrips; there upon the battery circuit to the primary coil will beclosed, and :1. hot spark generated in the secondary coil which isconnected by the wire 14 to the spark plug 3 whereby the charge will beignited.

What-I claim as new is:

1. In a device of the character described, in combination a cup-shapedcasing, four metal contact strips arranged in two series and in parallelrelation, a bar having its opposite terminals fixed against oppositepoints of the wall of said'cup, the intermediate portion of said barbeing flattened and formed with an aperture, a metallic switch memberconsisting of an intermediate portion formed with an elongated slot andat opposite ends with depressed contact shoes arranged to connect incontacting relation the first and third, or the second and fourth ofsaid contact strips, said switch member also formed at opposite endswith upwardly projecting terminals having openings through which saidbar projects, a screw bolt extendin vertically from the bottom of saidcup an projcctin through the aperture of said bar, a nut is readed onthe upper end of said bolt and engaging the flattened portion of saidbar and coiiperating to press said contact shoes against said strips, anoperating handle for slidahly actuating said switch member, and a springcoiled around said bar and bearing against the wall of said cup andagainst one of said upwardly projectin terminals, said slot being of alength to a low said switch member to move upon either of the endmost ofsaid strips.

2. In a device of the kind described, in combination, a casing,a rodextending transversely of and connected thereto, a switch member havingtwo depressed contact shoes at opposite ends thereof, said switch memherbeing slidahly guided upon said rod, a pair of contact arms mounted insaid casing, a sprin switch member'out of engagen'ient with said contactarms, and a tubular handle slidably projecting into the wall of saidcasing, being secured to said switch member so as to actuate the sameand telescopically fitting said rod.

In testimony whereof I :iltix my signature.

HENRY A. LYON.
